Hi Don,my name is XXXXX XXXXX I will be assisting you today.Can you get me the complete model number.Some of the ovens have a kit that is required.Please keep in mind,I am not there and need your input to correctly diagnose your problem.

It just has one electric oven. The wall unit has a warming drawer and a microwave, but they are operating independently of the oven control and still functon completely. It is the oven that is not functional because the display has gone out. The touch controls, bake, broil, convection, etc. beep when you touch them, but you can not tell what is happening becouse the display is out.

You will need to order kit number 702450 and install ALL of the parts in the kit.It comes with instructions and all the parts needed to fix the dim display with updated parts.How old is this oven? You may call Bosch and see if they will cover this for you.

You can buy the part directly from thermador by part number.The kit consist of a new display head,main power relay board,and keypad harness.You will have to partially remove the oven to complete the repair.

Rob, recall that I have a 3 unit wall system with a microwave then a warming drawer, and then the oven. I did get access to the control panel by removing the grill around the microwave and then removing the 2 screws holding the face plate of the control panel. I have removed the display head, but then your instructions are to install the replacement control panel display and reassemble the oven. It appears to me that I need to continue removing the sheet metal plates and install the new relay board and not reconnect the new display head at this point. Also you reference "insets and figures" in your instructions. Are you able to also send these "insets and figures"?
